Blue Grotto — Qrendi

What is the Blue Grotto?

The Blue Grotto is a complex of sea caves and a natural arch in the cliffs of Malta's south coast, near the village of Qrendi. On bright mornings, sunlight passes into the clear water and reflects off the pale sand and minerals on the cave floors, filling the caverns with intense shades of blue.

Where is the Blue Grotto?

The caves are on the south coast, reached from the small fishing inlet of Wied iż-Żurrieq. A roadside viewpoint nearby gives the classic photograph of the main arch, with the islet of Filfla out to sea.

How the Blue Grotto formed

The caves were carved over millennia by the sea working at the base of the limestone cliffs, opening caverns and an arch. The vivid colour is an optical effect: the combination of clear Mediterranean water, a reflective sandy seabed and the angle of the morning sun produces the deep blues that give the grotto its name. Light is best in the morning.

What to see at the Blue Grotto

• Boat trips that pass through the main arch and into several caves.
• The roadside viewpoint overlooking the arch and Filfla.
• Snorkelling and swimming from the Wied iż-Żurrieq inlet.
• The dramatic south-coast cliffs.

Significance

The Blue Grotto is one of Malta's best-known natural attractions and a classic boat excursion. Its position near the prehistoric temples of the south coast makes it an easy addition to a day of sightseeing in the area.

Visiting the Blue Grotto
